Mamoru lives with his older brother and his wife Miki. One day, when I was resting with a cold, Miki took care of me and I became delusional about the bodies I touched. However, Mamoru was shocked when he witnessed Miki's love affair with his tutor and was burned with desire. Alluding to a forbidden love affair, he blackmails Miki and sneaks into her husband's sleeping couple's bedroom and approaches Miki.
